Description

Technical Field

[0001] This application relates to the field of electricity, specifically to power supply technology. Background Art

[0002] The imbalance of power grid load over time is a major problem faced by the current power system.

[0003] In order to encourage users to stagger their electricity usage times, the power grid system has introduced a time-of-use electricity price plan. By setting peak electricity prices and off-peak electricity prices, it guides electrical equipment to flexibly use the idle periods with relatively abundant power supply.

[0004] However, some people are not sensitive to electricity prices. Therefore, the time-of-use electricity price plan has little effect on this part of the population.

[0005] Therefore, there is a need for an electrical equipment that does not require users to actively intervene, can finely balance the peak and valley at different micro-time periods for different locations in a timely manner, and can also be turned on by network control. Utility Model Content

[0006] The purpose of this utility model is to provide an electrical equipment with intelligent power grid interconnection function to solve at least one of the above technical problems.

[0007] The technical problems solved by this utility model can be achieved by the following technical solutions:

[0008] An electrical equipment with intelligent power grid interconnection function includes an electrical equipment with a mains plug. The electrical equipment includes a power supply part and a function system. The power supply part is connected to the function system to supply power to the function system. Its characteristics are as follows:

[0009] It also includes a timing switch system with at least one timed-on period. The timing switch system has a control system and a switch element;

[0010] The control system has a parameter input end for accepting parameter settings and a switch control output end for controlling the opening and closing of the switch element;

[0011] The switch element has a controlled input end that is controlled to be connected;

[0012] The switch control output end of the control system is signal-connected to the controlled input end;

[0013] The power supply part is power-connected to the control system;

[0014] The power supply part is also connected to the function system through the switch element;

[0015] The timing switch system adopts a timing switch system with network control function. The timing switch system with network control function is provided with a network signal input terminal for setting the timing-on period;

[0016] The timing switch system is also provided with a manual input component for setting the timing-on period.

[0017] In the above design, the manual input component is used to set the timing-on period for the timing switch system. The electrical equipment delays the running time of the electrical equipment to the pre-set low grid valley time period through the timing switch system. The beneficial effects are as follows: on the one hand, the electricity price in the low valley stage is cheap, which can save the electricity cost; on the other hand, running the electrical equipment during the low electricity consumption valley period can balance the load of the power grid and is beneficial to the stable operation of the power system.

[0018] Further, the manual input component includes a numeric keypad. The numeric keypad is a parameter setting device adapted to the control system and has a parameter output terminal. The parameter output terminal is connected to the parameter input terminal of the control system.

[0019] The numeric keypad is provided with keys numbered from 0 to 9. Its function is to manually set the running time period of the timing switch system. By setting the running start time period to the low valley period through the numeric keypad, it can not only save the electricity cost but also be beneficial to balancing the idle load of the power grid.

[0020] Further, the manual input component also includes a manual switch. One end of the manual switch is connected to the power supply part, and the other end is controllably connected to the switching element to control the function system to run immediately.

[0021] The beneficial effect of retaining the manual switch is that if the timing switch system has already set the opening time period but it has not reached the opening time period yet, and there is an urgent matter that needs to be started immediately, such as getting the news that the power grid is about to be maintained. At this time, it is necessary to immediately run the electrical equipment, and the manual switch can be used to handle this scenario. When the manual switch is pressed, the switching element is turned on and the electrical equipment is immediately turned on.

[0022] Further, the electrical equipment is a charging pile. The function system includes a step-down and rectification device for converting commercial power into direct current, and also includes a charging control system. The charging control system is a control system for regulating the direct current. The regulated direct current is transmitted to the electric vehicle through the charging socket;

[0023] The charging control system is also provided with an input device for setting the charging completion time limit.

[0024] In the above design, the charging control system can adjust the starting power according to the starting time and the charging completion time limit to balance the power grid.

[0025] Grid balance means that the supply-demand relationship of the power grid approaches a stable state, that is, the power generation in the power system is roughly equal to the power consumption, or the system can quickly respond to any minor supply-demand mismatch to ensure the stable operation of the power system. When the power grid tends to be balanced, it can guarantee the continuity, reliability, and security of power supply, thus meeting the electricity demand of users.

[0026] In a power consumption scenario, there is a charging pile device for charging an electric vehicle. The electric vehicle is connected to the charging pile at 6 pm. Without the intervention of a timing switch system, the charging pile device starts charging immediately after being plugged in until it is fully charged. At this time, it is still in the peak period, and for nearly 6 hours, peak electricity prices are used. Since it takes about 8 hours for an electric vehicle to be fully charged, the time using off-peak electricity prices is less than 2 hours, and nearly 75% of the time occupies peak electricity consumption and pays peak electricity prices.

[0027] With the intervention of the timing switch system, the charging pile device can avoid peak hours and start charging during off-peak hours, which not only saves the electricity cost but also greatly improves the smoothness of the power grid power supply.

[0028] Furthermore, the electrical appliance is a refrigerator, and the functional system includes a temperature control system and a compressor. The temperature control system has a temperature input interface for receiving temperature settings;

[0029] The electrical appliance also includes a networking device connected to Wi-Fi; the networking device has a control signal output terminal, and the control signal output terminal is connected to the network signal input terminal of the timing switch system;

[0030] The networking device also has a set temperature output interface, and the set temperature output interface is connected to the temperature input interface.

[0031] In the above design, a networking device connected to Wi-Fi is provided in the electrical appliance. The networking device can receive an opening instruction for the electrical appliance from the network. For example, the electrical appliance can be remotely controlled through a mobile phone APP.

[0032] In a power consumption scenario, when the power grid issues a maintenance notice, the electrical appliance can be remotely controlled through a mobile phone APP to avoid losses caused by the power grid maintenance time:

[0033] For example, if the electrical appliance is a refrigerator, before the expected power grid maintenance time, the refrigerator can be started with the mobile phone APP to perform a forced cooling of the freezing area once, and then the compressor can be put into a sleep state to avoid the reverse current generated by the inductance effect of the compressor from damaging the refrigerator itself or even impacting the power grid.

[0034] For example, if the electrical device is an air conditioning system, the air conditioner can be started with a mobile phone APP before the expected grid maintenance time. For the heating function, increase the heating temperature; for the cooling function, lower the cooling temperature. Then, before the grid maintenance time, let the compressor enter the sleep state in advance to avoid damage to the air conditioning system caused by the reverse current generated by the inductance effect of the compressor, and even avoid impacting the power grid.

[0035] For example, if the electrical device is a fish pond aeration system, the aerator can be started with a mobile phone APP before the expected grid maintenance time to provide strong aeration to the fish pond once to avoid the death of fish due to lack of oxygen.

[0036] For example, if the electrical device is a charging pile device, the charging pile can be started with a mobile phone APP before the expected grid maintenance time to complete the charging of the electric vehicle before the grid maintenance time.

[0037] Furthermore, the switching element uses an Insulated Gate Bipolar Transistor G4PH50UD.

[0038] An Insulated Gate Bipolar Transistor (IGBT) is a semiconductor device that can withstand high voltages and high currents, especially with a switching speed reaching the microsecond level.

[0039] The maximum breakdown voltage of G4PH50UD is 1500V, and the maximum current can reach 40A, which can meet the power consumption requirements of the above-mentioned charging piles, refrigerators, air conditioners and other devices.

[0040] The electrical device of the present utility model delays the operation time of the electrical device to the pre-set low grid valley time period through a timing switch system. The beneficial effects are as follows: on the one hand, the electricity price in the low valley stage is cheap, which can save the electricity cost; on the other hand, operating the electrical device during the low electricity consumption valley period can balance the load of the power grid and is beneficial to the stable operation of the power system.
